| Summary | 0024673: MP Issues April 10 | ||||
| Description | We could not connect at all using Steam P2P. Connecting via Steam C-O was very flaky, it would often take multiple attempts but would usually work in the end. Other problems. Sometimes a bunch of ships on a planet will disappear for 5 seconds or so, then reappear. In general it happens on a per-\ faction basis; like all the player ships will disappear (but the player-allied scourge wil lbe visible), or all the AI ships will vanish \ on a planet and the planet will show as unowned, then it will reshow as owned by the AI. <This error happened a ton> 4/10/2021 9:10:11 PM 2.773 CLIENT Hit exception during HandleAutobuild debugCode 5300 System.NullReferenceException: Object reference not set to an instance of an object <This error also happened frequently> 4/10/2021 9:05:43 PM 2.773 CLIENT BLARRRGH!

Also, partway through the game we were all granted the Achievements related to winning our game with the current settings (like "Beat this AI type", "Beat the game with these factions enabled", etc... This did not seem to correspond to any other errors |

This may help, but is not directly related to the things you reported: * Fixed a fairly rare bug that was causing units to not serialize properly sometimes. It seemed to be related to the incomingshots list on units, which is something that really should only be sent in fully network syncs but should not be sent to disk or as part of smaller network syncs. ** Essentially, because of the many improvements made to multiplayer efficiency, this unfortunately had created a miniature version of Russian Roulette (some sort of fantasy chain gun with 2000 slots but only one with a bullet in it), where if you got tagged with it, it would corrupt your save. ** Thankfully, autosaves are a thing, and in the example save that had this issue, there was an autosave from literally 20 seconds earlier that did not have the problem. And with extensive testing on the same save, we couldn't get it to replicate. ** That said, some of the persistent intermittent errors that folks were seeing in multiplayer were a lot less rare (because multiplayer takes a lot more tries at Russian Roulette, not because the actual odds changed), and this is probably an accidental discovery of what those were. |

Going from top to bottom in your list: * Fixed a variety of exceptions that could happen in HandleAutobuild() mainly in multiplayer, on the host or clients, due to cross-thread racing. Technically it could also happen in solo play, but we haven't seen any evidence of it actually doing so. |
|
|
* The "BLARRRGH! Only authorized to execute through frame" error is now silenced. That... really wasn't actually a problem that was worth even complaining about. This was something that was showing up lately in at least a few multiplayer sessions, though something else seemed to be going on with them in general. |

This error that you describe, by the way, I suspect is a downstream error thing: "Other problems. Sometimes a bunch of ships on a planet will disappear for 5 seconds or so, then reappear. In general it happens on a per-\ faction basis; like all the player ships will disappear (but the player-allied scourge wil lbe visible), or all the AI ships will vanish \ on a planet and the planet will show as unowned, then it will reshow as owned by the AI." This sounds like some sort of error during faction sync causing some data loss. Given the many other errors, I'm not too worried about this being a persistent thing. Now that the Steam Sockets code is multi-port, this should be less of an issue in general, but I'll adjust it if I need to. Mainly just reducing the obvious exceptions should solve that one, though. |

* Fixed an issue in CheckForInternalShipDeployment_ReinforcementLocations() that could happen on MP clients, which really did not need to be running that logic anyhow. |

Hooookay... this one should not even be possible as it already stands: if ( ArcenNetworkAuthority.DesiredStatus != DesiredMultiplayerStatus.Client ) ArcenDebugging.ArcenDebugLog( "Blank FleetMembership for ship of type " + Entity.TypeData.DisplayName + "!", Verbosity.ShowAsError ); But that happened on a client for you. I think a client was somehow having a desiredstatus of singleplayer, which would have been all sorts of trouble. THAT said, the logging code is like this: switch ( ArcenNetworkAuthority.DesiredStatus ) { case DesiredMultiplayerStatus.SinglePlayerOnly: fullMessageMaybeStack += "\tSINGLEP"; break; case DesiredMultiplayerStatus.Client: fullMessageMaybeStack += "\tCLIENT"; break; case DesiredMultiplayerStatus.Host: fullMessageMaybeStack += "\tHOST"; break; } So the fact that it says client in front of it must mean that it was in client mode. It is possible that this was a delayed message, and it had shifted in and out of client mode somehow over the span of a few milliseconds, but that would be very alarming. Basically if it was in solo mode when on the BG thread, and it queued the message for a delayed write a few ms later, and then it was back in client mode by then? That makes no sense at all, but if we see more signs of something like that, then I'll have to take more of a look. For now I'm going to chalk it up to "I guess things get strange after errors." But I will keep an eye out. |

You fixed this one: <This error happened for everyone> 4/10/2021 9:35:46 PM 2.773 CLIENT Exception in DoPerSimStepLogic_OnMainThreadAndPartOfSim for faction AI Praetorian Guard(Index 37)\ , so will not run any more of those until a reload of the save.

* Fixed an exception that could happen in SpawnRaiders() on Marauders in multiplayer clients. Again not something they needed to ever do, it's left to just the host now. |
|
|
* Fixed a number of possible cross-threading issues in CalculateShipsThatYouCanCapture(), which were vastly more likely to happen on MP clients. |
|
|
* Fixed several more cross-threading bugs that could happen in WriteFleetTooltip(), again way more commonly on MP clients than anywhere else. |
|
|
Okay, that's the last of actionable things: * Fixed another cross-threading bug that could happen in Hacking_GrantShipLine_DontDestroyTarget.GetCanBeHacked(), again mainly on MP clients. The obvious potential errors have been fixed, but then also it will now show in the ui an "error at debug stage x" message if it still runs into one. It will also silently log the error for us to look at more later, and to be able to further fix if need be. Thanks so much for all of these, and the way that you pull them out! The whole achievements thing is very strange, but again I have to guess that it's probably a downstream error. Hopefully as these primary errors are put to pasture, the downstream ones will also just quiet down. |
|
|
My goal when opening a bug is to make it as easy as possible for you to fix! |
|
|
That is greatly appreciated! :) |
